What are the signs of nutrient deficiencies in ficus bonsai?
I've noticed some yellowing leaves on my ficus bonsai recently, and it’s got me worried! Living in Dubai, my nutrient solutions are custom-tailored for leafy greens, but I’m questioning if they’re suitable for my ficus bonsai as well. I’ve been adjusting the pH and conductivity levels, but I’m not sure what specific signs to look for that might indicate nutrient deficiencies. My experience is mostly with leafy greens, where signs are pretty direct, but bonsai seems a bit more subtle. Can anyone help with identifying symptoms of deficiencies specific to ficus bonsai? Any additional insights into correcting them would be greatly appreciated!
